Answer 2

To find the cost of the purchase for each boy, we need to divide the total cost by the number of boys. In this case, Sasha and Vova went to the store to buy notebooks. Sasha bought 4 notebooks, while Vova bought 5 notebooks. The total cost of all the notebooks was 1 ruble and 98 kopeks.

To find the cost per notebook for each boy, we can divide the total cost by the total number of notebooks purchased. Let's calculate it step by step:

1. Calculate the total number of notebooks purchased: Sasha bought 4 notebooks, and Vova bought 5 notebooks. So, the total number of notebooks purchased is 4 + 5 = 9 notebooks.

2. Calculate the cost per notebook: To find the cost per notebook, we divide the total cost by the total number of notebooks. The total cost is 1 ruble and 98 kopeks, which can be written as 198 kopeks. So, the cost per notebook is 198 kopeks divided by 9 notebooks.

Now, let's calculate the cost per notebook for each boy:

Sasha's purchase:

Sasha bought 4 notebooks. To find the cost of Sasha's purchase, we multiply the cost per notebook by the number of notebooks Sasha bought.

Cost per notebook: 198 kopeks / 9 notebooks = 22 kopeks (rounded to the nearest whole kopek)

Sasha's purchase: 4 notebooks * 22 kopeks = 88 kopeks

Vova's purchase:

Vova bought 5 notebooks. To find the cost of Vova's purchase, we multiply the cost per notebook by the number of notebooks Vova bought.

Cost per notebook: 198 kopeks / 9 notebooks = 22 kopeks (rounded to the nearest whole kopek)

Vova's purchase: 5 notebooks * 22 kopeks = 110 kopeks

Therefore, Sasha's purchase cost 88 kopeks, and Vova's purchase cost 110 kopeks.
